Organometall‐Imide – Höhervalente Derivate der d‐Metall‐Säuren, 1 Neue Organometall‐Imide des Molybdäns und Wolframs — die direkte Einführung der Cyclopentadienyl‐Gruppe durch Maskierung der hohen Oxidationsstufe

Organometallic Imido Complexes – Higher Valent Derivatives of the d‐Metal Acids, 1. – New Organometallic Imido Complexes of Molybdenum and Tungsten – Direct Introduction of the Cyclopentadienyl Group by Masking the High‐Oxidation State The molybdenum(VI)bis( tert ‐butylimido) complex MO(N t Bu) 2 ‐Cl 2 is converted into the novel organomolybdenum(VI) derivative (η 5 ‐C 5 H 5 )MO(N t Bu) 2 Cl ( 1 ) in excellent yield. The preparation of the pyridine complex W(N t Bu) 2 Cl 2 py 2 ( 2 ) provides a convenient starting material for an effective synthesis of the related complex (η 5 ‐C 5 H 5 )W(N t Bu) 2 Cl ( 4 ).
